This application is a non-provisional application which claims benefit of co-pending U.S. Patent Application Ser. No. 61/255,761 filed Oct. 28, 2010, entitled “Mobile Shower Unit”, which is hereby incorporated by reference in its entirety.

FIELD OF THE INVENTION

The present invention relates generally to a personal cleaning unit, such as a shower, and more particularly to a collapsible shower that is fully portable yet provides a shower experience consistent with a permanent shower unit installed at a location, such as a dwelling or facility.

BACKGROUND OF THE INVENTION

There are numerous institutes and individuals that have a need for an apparatus that provides a personal portable cleaning location. These institutions and persons include the military, safety organizations such as law enforcement, fire department, emergency medical services and the like, health care providers, and the camping and outdoor enthusiasts. These organizations and people generally have a need for a cleaning unit that can adequately provide a personalized cleaning area and yet is easily transported between locations in a smaller or more compact state. Once at a location where those persons and/or organization members need or desire to clean themselves or others, an apparatus needs to have the capability of satisfactorily filling that need and transforming into a deployed or expanded state.

There have been several attempts in the art to provide equipment that fill this need for these various organizations. Some prior attempts have included a simple spigot or spout used to direct water as desired by a user. Other attempts have been directed at forming a shower unit through various usages of frames, shower curtains, and pipes for water flow.

Several of these prior attempts have fallen short in one or more areas. For example, some lack an easily assembled unit. Others lack a base or support structure that separates the user, and more particularly his or her feet, from the surrounding ground and/or surface. Others lack sufficient structure to maintain the shower integrity through moderate, or even mild, wind conditions in an outdoor ambient environment. Still others lack construction features that provide enough durability to the cleaning unit for multiple assemblies and usages by numerous individuals.

What is needed then is a mobile cleaning unit, for example a shower unit, which is collapsible and can easily be assembled. Preferably this unit includes a base that provides for fluid flow and separates the person cleaning within the unit from the surrounding ground and/or surface. Preferably this unit has a durable structure that can withstand ambient conditions yet can collapse into itself and provide an easily portable unit that can be taken to a new location. This cleaning unit is lacking in the art.
